hi all by what i have read its 23 spline and about 7 1/4 inch. can anyone confirm size in mm, part numbers and if its only the sierra 2.3d that uses them. cheers

Yes, I wasn't absolutely sure, myself. I was advised to give Yuk a ring (yep, that's his name!) at yukspeed. This is what I did, and he supplied it.

You might also wish to look at SBD Motorsport. Not quite as cheap, but pretty helpful.

Also there is QED who are also helpful suppliers.

(but go to Yuk first).

Hope this helps.

SIERRA 2304cc diesel clutch plate 232mm x 25.4mm x 23 splines (9 1/8"

190x25x23 QH part No C784AF any good?

Surely a 2.3 clutch is going to be bigger than 7.5", as that a 1300 mk2 escort size, sure it was an 8.52 clutch on the one I stripped. Have got a 2.3 5 speed type nice if any one is after one.
